Abstract: A swash plate type compressor comprises a cylinder block cooperating to form therein a compartment accommodating therein a swash plate and also serving as a suction chamber of the compressor, and a drive shaft rotatably supported in the cylinder block and having formed therein an axial discharge passage connecting front and rear discharge chambers. The compressor further includes a pair of front and rear rotary type suction valves mounted on the drive shaft for rotation therewith and fitted in bores formed centrally in the cylinder block such that one axial end thereof is exposed to suction pressure and the other end to discharge pressure of the refrigerant gas. Each suction valve has formed therein a passage which is in constant communication with the swash plate compartment and is operable to bring its passage in communication successively with fluid working chambers in synchronism with the rotation of the drive shaft. The drive shaft is formed with a lubricating oil hole extending radially from its central discharge passage to its outer periphery and directed to feed lubricating oil toward the sliding contact surfaces between the suction valve and its accommodation bore.

Abstract: A reciprocating compressor includes double headed pistons forming front and rear sets of compression chambers on either side thereof and a pair of tapered rotary valves arranged for introducing a coolant gas into the compression chambers. The valves are urged into contact with valve chambers by springs and a drive shaft is urged in one axial direction by a prestress mechanism. The valve urging force for one rotary valve is different from the valve urging force for the other rotary valve, so that the rotary valves operate at different times and over different distances and the movements of the rotary valves are controlled to move the drive shaft in the same axial direction as the direction of the prestress mechanism.

Abstract: A piston type compressor is disclosed, which comprises a cylinder block having axial cylinder bores, pistons defining compression chambers in the bores, a drive shaft, and a gas suction and discharge chambers in a housing. A valve receiving chamber is formed around the drive shaft in the cylinder block, for accommodating a rotary valve which rotates in synchronism with rotation of the drive shaft. The rotary valve has a suction passage formed therein for providing gases from the gas suction chamber to a compression chamber during the chamber's gas suction stroke. A plurality of gas communication passages are formed in the cylinder block in association with the compression chambers, each having a first port open to the associated cylinder bore and a second port open to the valve receiving chamber. The first port is located at a position (P2) apart by a predetermined distance (L) from a top dead center position (P1) of the associated piston. The rotary valve has a bypass passage formed therein, for permitting one communication passage, isolated from both the compression chambers and the gas suction chamber, to communicate with another communication passage corresponding to a compression chamber in a compression stroke.

Abstract: Provided is a compressor, in which discharge capacity is changed by an actuator, exhibiting high controllability while realizing reduction in size. In the compressor, a movable body includes a rear wall, a circumferential wall, and a coupling mechanism. The coupling mechanism includes a first arm provided with a first pulling point and a second arm provided with a second pulling point. In the compressor, when the inclination angle of a swash plate is increased, the movable body pulls the swash plate via the first and second arms. At this time, in the compressor, pulling force can be applied at two points, i.e., at the first pulling point and the second pulling point. Consequently, in the compressor, even when the size of the rear wall and the circumferential wall is increased, the rigidity of the first and second arms can be made lower.

Abstract: A refrigerant gas suction valve mechanism for a reciprocating piston type compressor is disclosed. The mechanism has a drive shaft rotatably disposed in a gas receiving chamber where uncompressed gas is introduced, Double- headed pistons provided in cylinder bores compress the gas when the pistons move from the bottom dead center to the top dead center. A suction port selectively permits and blocks communication between the suction passage and the compression chambers. A resilient member holds a rotary valve in contact with an inner wall of a recessed chamber with predetermined force. The suction port is maintained at a predetermined distance from a point where the pistons reach the top dead center so that the suction port is closed by the pistons before the pistons reach the top dead center.
